Abstract: A composite material includes a resinous particulate material, and an inorganic particulate material having a particle diameter being smaller than that of the resinous particulate material, fused welded onto a surface of the resinous particulate material, formed of an inorganic oxide, and including OH groups generated by fuse welding in the surface. The composite particulate material exhibits a degree of sphericity of 0.8 or more, and a has volumetric average particle diameter of from 0.1 to 100 μm.
